A new TV spot has been released for Captain America: The Winter Soldier and it may well give us a heads up on a potential plot point/major spoiler. See if you can figure it out (if you're a Marvel comics fan you'll already have put two and two together from the first trailer and released pics, one of which I'm putting below). If you want to see what I think it is highlight the invisible text under the image with your mouse. :)
All clues point towards this dead body being Nick Fury/Samuel L. Jackson!!!
